Title: A method for estimating the temperature in an internal combustion engine
Inventor: PARISI FILIPPO
IPC: G01K7/20
Filed: 2008-06-27
Abstract: A method for estimating the temperature in an internal combustion engine comprises the steps of providing a sensor resistor (RTD) in the internal combustion engine, the sensor resistor (RTD) having a predetermined resistance-temperature characteristic, measuring a sensor voltage (VRTD) across the sensor resistor (RTD), calculating a resistance value of the sensor resistor (RTD) based on the sensor voltage (VRTD) and estimating the temperature using the resistance value and the resistance-temperature characteristic. The method is characterized in that it further comprises the steps of connecting, in series to the sensor resistor (RTD), a first branch (10a) of a current mirror arrangement (10), connecting a reference resistor (Ro) in series to a second branch (10b) of the current mirror arrangement (10), measuring a reference voltage (Vo) across the reference resistor (R0) and calculating the resistance value of the sensor resistor (RTD) based on the sensor voltage (VRTD) and the reference voltage (Vo). The method ensures the measurement is not dependent on the reference voltage source VADCof the converter ADC, is not dependent on the supply voltage source VCCand is not dependent on the temperature.

Title: Measuring surface profile of golf clubs, calibrating image capture device and apparatus for preparing a measurement specimen by taking a cast of a surface
Inventor: OTTO STEVEN
IPC: A63B69/36
Filed: 2009-04-30
Abstract: There is described a method and apparatus for testing a surface of a golf club to determine conformance or otherwise with at least one of the requirements of the Rules of Golf. The apparatus comprises a moulding dam (7) for producing a moulded sample / cast (20) having a surface corresponding to the surface to be measured, and a cutting apparatus (23) for cutting a specimen or "slice" from the moulded sample / cast. An image of a profile of the specimen / slice is captured and dimensions of features of the surface profile of the golf club determined from the captured image. The specification also discloses apparatus and a method for calibrating an image capture device in order to produce a dimensionally accurate trace of a profile of a surface from a captured pixellated image of the profile. The method of calibration involves capturing a pixellated image of a calibration grid, detecting pixel co-ordinates of predetermined points on the image, determining distance between selected pairs of points, determining local scale factors for a number of points on the captured image by comparing pixel distances associated with those points with known dimensions of the calibration grid; predicting scale factors for pixels of the captured image on the basis of the predetermined scale factors and applying the predicted scale factors to pixels of the image to convert pixel co-ordinate data to dimensional co-ordinate data. The step of predicting scale factors may comprise generating an nth degree polynomial equation to relate local scale factors to pixel co-ordinates and finding polynomial coefficients which best fit the measured scale factor values and their associated pixel co-ordinate data. The polynomial is then applied at each pixel location to determine a scale factor for that location.

Title: Testing whether a node is configured to correctly process high priority data by increasing the transmission rate and measuring change in quality of service
Inventor: BLUM PAUL
IPC: H04L12/26
Filed: 2009-09-24
Abstract: A technique for ensuring that a node that carries high-priority protocol data units and low priority protocol data units is properly configured to accord the high-level protocol data units priority treatment is described. In accordance with the illustrative embodiment, two streams of protocol data units are transmitted through a node to be tested. One stream comprises high-priority protocol data units, and the second stream comprises low-priority protocol data units. The processing capabilities of the node are then burdened by increasing the frequency of protocol data units transmitted to it, so that the node is compelled to treat the two streams differently if it is configured correctly. The decision on whether the node is configured correctly is made based on any observed drop in a quality of service as a consequence of the increase in transmission rate. The quality of service monitored could be delay, jitter or bit error rate.
Patent GB-670929-A (GB)
Title: Improvements in or relating to a method of preparing uronic acids and derivaties thereof
IPC: C07H7/033
Filed: 1950-04-24
Abstract: Glycosides are oxidized to glycuronosides with 65-100 per cent nitric acid at 20-100 DEG  C. in the presence of nitrous acid, a nitrite salt or nitrogen trioxide gas, there being at least one mol. of nitric acid per mol. of glycoside.  Preferred conditions are 30-45 DEG  C. for 8-20 hours.  Thus a solution of a glycoside and sodium nitrite in 65-75 per cent nitric acid is prepared at 45-50 DEG  C. and maintained at 35-45 DEG  C. for 8-20 hours.  The reaction mixture is then heated to 90-100 DEG  C. to remove excess oxidant, preferably with 0.5-1 per cent of formaldehyde (or methanol) and the glycuronoside purified by solvent-extraction and/or adsorption. Dicarboxylic acids are precipitated as calcium or barium salts. Finally, hydrolysis is effected with an acid or a cation-exchange resin, the glycuronic acid or its lactone being obtained by crystallisation.  If sodium nitrite is used as oxidation catalyst, it may amount to 0.1-0.5 per cent by weight of glycoside. Alternatively, the by-product gases from a previous oxidation may be used as catalyst.  Examples show the preparation of methyl-, ethyl- and cyclohexyl-glucuronides from the corresponding glucosides, and glucuronolactone by hydrolysis. Other examples show the oxidation of trehalose and starch to uronic acids.

Title: A process for the conversion of normal butane into isobutane
IPC: C07C5/27
Filed: 1946-04-01
Abstract: Gas consisting mainly of n-butane and containing small proportions, e.g. some tenths per cent by volume, of higher boiling hydrocarbons, is freed from the latter as by rectification, prior to feeding to a reactor for vapourphase isomerization to isobutane using aluminium chloride as catalyst, whereby the catalyst life is lengthened.  The initial gas may be treated together with reaction product of a previous operation; first to separate isobutane, and then to remove hydrocarbons higher boiling than n-butane.  In an example, the initial gas containing 85 per cent n-butane, 15 per cent isobutane, and some tenths per cent higher boiling hydrocarbons by volume is passed with 5 per cent hydrochloric acid over aluminium chloride on an equal weight of activated alumina at 100 DEG  C. and 15 atmos., vaporous aluminium chloride being introduced in the gas-flow from a pre-converter containing the same catalyst.
